DOOR-LOCK.

Application filed June 3, 1915. Serial No. 31,822.

To all whom it may concern:

Be it known that I, BAYARD E. TAYLOR, a citizen of the United States, and a resident of the city of Oak Park, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Door-Locks; and I do hereby declare that the following is a full, clear, and eXact description of the same,'referenc'e being had to the accompanying drawings, and to the numerals of reference marked thereon, which form a part of this specification.

Considerable difficulty .has been experienced in securing a lock adapted for auto mobile doors which will withstand the severe conditions to which the same is subjected without becoming loose'and allowing the door torattle. In the past locks have been used in conjunction with bumper strips mounted upon the frame for the door against which the door is tightly thrust by the loclrin mechanism to revent rattlin of the door, but such strips soon become worn and fail in their purpose. Then, too, in some instances, provision is made by supplementary locking mechanism on the door to lock the door in an open position, thus increasing the complication of parts andin many instances taking the form of unsightly devices which also, when not in use, hang loosely in a manner to easily rattle and also may become caught upon the garments of persons entering or leaving the car.

It is an object therefore of this invention to construct a locking device for attachment to doors, windows, or the like, to positively lock the same in a closed position in a manner to prevent rattling thereof and also capable of locking the door in any open position desired.

It is also an object of this invention to construct a locking device embracingeccentrically operated means for positive engagement with a flexible element to lock the door in closed position and with means operating under pressure to clamp said'ele ment to hold the door in any open position of adjustment. v

It is also an object of this invention to provide a door locking device embracing telescoping members having concealed therein a flexible steel strap element which has sliding enga ement with a locking'device whereby mechanisms within the looking device may engage said steel strap to lock the door in an open or closed position,

positively holding the same in a fixed position when so locked.

It is also an object of this invention to construct a locking device embracing a plurality of locking mechanisms independently operatable to coact with a unitary flexible element to retain a door in open or closed position. Y

It is furthermore an important object of this invention to constructa door locking Specification of Letters Patent. Patented N 13, 191

device wherein spring actuated latching mechanisms'are impelled into release position by eccentrically operating means acting against spring tension, said latching'means acting to en age through an aperture provided in a flexible element which is adjust ably connected to the door frame and havingslidable movement through the locking device whereby a yieldable but positive lock for the door is assured to hold the same closely in its framewhen closed.

It is finally an object of this invention to construct locking mechanisms actingyieldably to hold 'a door tightly closed in its frame or maintain the same in anopen. RClJUStQCl position in a manner to prevent rattling of the door;

The invention (in a preferred form) is illustrated in the drawings and hereinafter more fully described.

As shown in the drawings:

The reference numeral 1, indicates as a whole a door or window mounted in a frame 2, by means of hinges 3, said door and frame forming a part of any structure whatsoever. Rigidly secured upon the door 1, is a casing comprising a front plate 4, having side walls 5, integral therewith and reinforced by integral ribs 6, and with a rear cover plate 7, adapted to be secured on said side walls 5, by means of screws 8, as shown in Fig. 8. Formed upon the outer surface of the wall 4, at one end thereof, is a boss 9, which is apertured and within which is journaled a short shaft 10, having a toothed eccentric 11, integral tierewith at one end, and a handle 12, for turn ing said shaft secured in any suitable mair ner, on the other end thereof.

Projecting perpendicularly from the inner surface of the eccentric 11, is a pin 13, and engaged thereon is one end of a connecting rod 1 1, the other end of which is engaged upon a pin 15, which projects upwardly from and is integral wit-h or rigidly secured upon a slidable plate 16, resting.

against the inner surface of the wall plate 4. The central portion of said plate 16, is cut away, as clearly shown in Figs. 3, 5, 6, and 10, and journaled between uprights 17, provided at one end of said plate is a long arm 18, provided with a latch member 19, and having also formed integral therewith two short arms or cam teeth 20. Said arm 18, at its free end, is provided with lateral extensions 21, which are recessed on their inner surfaces to receive seated therein coiled springs 22, as shown in Fig. 10, the other end of said springs seating in, recessed portions of the plate 16, said springs acting normally to impel said arm and latch 19, inwardly toward the plate 7. At the forward end of said plate 16, horizontal bosses 23, are formed on each side of the plate, and projecting outwardly therefrom in parallel relation are rods 24c, which slide through apertured brackets 25, provided on the inner surface of the wall of the casing.

lVound about each of said rods 24, are coiled compression springs .26, which, at their ends, bear against the lugs 23, and brackets 25, respectively, to resist movement of the plate 16, toward the eccentric 11, when said plate is moved in such a direction, due to rotation of the eccentric. A tooth or abutment 27, is provided on the interior of the casing at one end thereof, and is adapted to be engaged by the toothed eccentric, as clearly shown in Fig. 12, and when the eccentric bears against said tooth 27, the

pin 13, of the eccentric is past a dead center position. Consequently the pull on the eccentric exerted by the connecting rod 14, due to the compression springs 26, is re sisted, and the device thus retained under spring tension in. this position of adjustment with the plate 16, held toward the forward or eccentric end of the device.

Extending longitudinally slidably within the casing fiat against the rear'wall 7, thereof, is a flexible strap, preferably spring steel or the like, denoted by the reference numeral 28. Said strap is provided with a notch or aperture 29, therethrough, adapted to receive the latch 19, projected into engagementwith one edge thereof in the manner shown in Fig. 5, to lock the device when the handle 12, is rotated to ahorizontal position, and the cam into the position shown in Fig. 12. Integrally formed upon the rear end of the casing are eyes 30, adapted to receive engaged therebetween a tubular member 31, having a pin 32, extending through the end thereof affording, a pivotal connection between said tubular mem her and said eye members.- Said pin 32, is provided with a longitudinal slot therein through which said flexible strap element 28, extends, and the end of said strap is at tached to a plug element 33, threaded for adjustment into another tubular member 34, telescoped within said tubular member 31. Tightly threaded into the other end of said tubular member 34, is another plug 35, which fits into. a hinge bracket 36, and is adapted to receive a hinge pintle 37, inserted therethrough, said bracket being secured upon the frame 2, for the door or window upon which the device is used. As clearly shown in Fig. 9, the inner surface of the plate cover member 7, forming the inner wall of the casing, is grooved or recessed to receive the flexible strap 28, therein, so that proper disposition of said flexible element in all its positions within said casing is se cured. As clearly shown in Fig. 8, the rear cover plate 7, of the casing is provided with a pair of notches or slots '38, adapted to receive projected therethrough the arms 20, integral with the latch carrying arm 18, within the casing, to insure retraction of the latch member 19, from the slot 29, of the flexible element when the slidable plate 16, ismoved rearwa-rdly within said casing. A slot 39,.is also provided in said cover plate 7,10 afford clearance for the latch 19, when the same is projected through the slot provided therefor inthe strap, 28.

Another mechanism is provided for co action with the fiexible element 28, to effect locking of the door in any desired position,

and for this purpose an outwardlyprojecting boss 40, is formed at therear'end of the casing upon the front wall 4, and is apertured and internally threaded to receive a screw bolt 41, engaged therein, provided with an actuatlng head 42, whereby rotationof said bolt serves to move the same inwardly or outwardly, as the casemay be, in said boss. The inner end of said screw bolt 41, is provided'with a circular head 43, engaging in a T-shaped slot in a clamping foot 44, which, when thrust inwardly due to rotation of the screw bolt, is forced firmly against the flexible strap element 28, serving to clamp the same tightly'against the rear wall 7-, of the casing to hold the door in any position of adjustment. Said clamping foot 44, is prevented from longitudinal movement within the'casing, which might result in accidental disengagement thereof from the'head 43, by lugs 45, formed on each side thereof and bearing against the integral inwardly directed end walls 46, formed within the casing, as shown in Fig. 3, the arrangement, however, permitting movement of said clamping foot toward and away from the flexible strap element 28.

The operation is as follows: i

The device with the handle 12, in the horizontal position shown in Figs. 1, 2, and 5, is in locked position with the door closed, and in order to release the door to permit opening thereof, the handle 12, is rotated through an angle of ninety degrees and to a perpendicular position, thereby rotating the eccentric and permitting the plate 16, connected to the eccentric through the connecting rod 14, to move rearwardly, due both to rotation of the eccentric and also under the impulse of the compression springs 26. Such rearward movement of the plate 16, causes the latch member 19,- to move out of contact with the edge of the slot 29, in the flexible element '28, and the movement of the plate 16, continuing, also causes the arms 20, to contact the edge of the slots 38, in the cover plate 7, to causethe arm 18, and latch member 19, carried there by, to swing downwardly within'the casing, permitting free movement of the flexible strap element 28. As the door or window upon which the device is connected is opened, said flexible strap element 28, slides through the casing, and the plug member 38, to which it is securely connected, being mounted in the end of the tubular member 34, which is telescoped within the tubular member 31, said flexible strap element moves into orwithin said tubular member 31, as the telescoping elements are extended, thereby being concealed at all times and also protected from injury. The device acts automatically to lock the door when the door is swung-to closed positionydue to the fact that the slot 29, in the flexible element is swung into a registering position above forward end of the slot 29, in the flexible element. Such movement, of-course, .is resisted by the compression springs26, but due to the fact that theeccentric connection of the connecting rod on the cam element causes the cam to be disposed beyonda dead centersuch asshown inFig. 3, with the tooth of the cam 11, bearing against the abutment 27 within the casing, the compre's sion of said springs serves to hold the mechanisms in this. position until manually released by turningthe handle 12. If for any reason it is desired .to fix the door in any open position of adjustment, with the mechanisms controlled by the handle 12, in release position, the head 42, is rotated to move the screw bolt 4-1, inwardly, causing the clamping foot 44, to bear with pressure against the flexible element 28, holding the same frictionally from slidable movement within the casing and thus retaining the door in the position of adjustment desired. The interflttingtelescoping members 31 and 34, serve to protect and conceal the flexible strap member 28, and due to the manner in which the strap is connected to the member 34, by means of the threaded plug 33,-a feature of adjustment is obtained which permits the tension on the strapto be changed to suit conditions and takenp for wear of the parts. Said telescoping members also limit the opening movement of the door, thereby protecting the hinges from injury and also permitting. the use of a cheaper hinge than would otherwisebe necessary.

I am aware that various details of con struction may be varied through a wide range without departing from the principles of this invention, and I therefore do not purpose limiting the-patent granted otherwise than necessitated by the prior art.'
